If you use ChatGPT for work, you have probably uploaded the same file dozens of times. The same PDF, the same spreadsheet, the same brand guidelines — re-uploaded into every new conversation. OpenAI solved this with ChatGPT File Library, a persistent storage feature that launched on March 23, 2026. With File Library, your uploaded documents live in one place and can be pulled into any conversation without re-uploading. This guide walks you through everything you need to know about this feature: who can use it, how to access it, how to add files, and how to use them across multiple chats.
If you are a ChatGPT Plus, Pro, or Business subscriber, this feature is available to you right now — and it changes how you work with documents in AI chat entirely.
What Is ChatGPT File Library and Who Can Use It
ChatGPT File Library is a centralized storage area inside ChatGPT that holds your uploaded files persistently. Before this feature, any file you uploaded existed only within that specific conversation and was effectively lost when you started a new chat. With Library, files persist indefinitely until you manually delete them.
OpenAI announced File Library on March 23, 2026, rolling it out to paid subscribers globally. Here are the current availability details:
- Available to: ChatGPT Plus, Pro, and Business subscribers
- Not available to: Free-tier users; users in the European Economic Area, Switzerland, and the United Kingdom (regulatory restrictions)
- Platform: Web only at chatgpt.com — mobile apps do not yet support File Library
- Upload frequency: Plus allows approximately 80 file uploads per 3 hours; Pro subscribers have no limit
The supported file types cover the most common document formats used in professional workflows:
- Documents: PDF, DOCX, TXT
- Spreadsheets: XLSX, XLS, CSV, TSV
- Presentations: PPTX
- Images: JPG, PNG, WebP, and other common formats
File types that are not supported include video files, audio files, executable files (.exe, .app), and password-protected documents. Maximum file size is 512 MB for general files, 50 MB for CSV and spreadsheet files, and 20 MB per image. For the latest how-to guides on getting more out of AI tools, check our how-to section.
How to Upload and Access Your Files in ChatGPT Library
There are two ways to get files into your Library. The first happens automatically when you upload files in a regular chat. The second involves uploading directly to the Library itself. Both methods work equally well.
Accessing the Library in ChatGPT
Finding your Library is straightforward. Follow these steps:
- Open chatgpt.com in your browser and sign in to your Plus, Pro, or Business account
- Look at the left sidebar, below your conversation history
- Click Library to open the file browser panel
- Your Library will display all saved files with previews, file names, file types, and upload dates
Inside Library, you can search for specific files, filter by file type, and see whether a file was uploaded by you or generated by ChatGPT (such as code outputs or created documents). Previewing a file shows a formatted layout directly in the browser without needing to download it.
Uploading Files Directly to Your Library
ChatGPT automatically saves files you upload during regular conversations. But you can also add files proactively before starting any chat. Here is how to upload directly to Library:
- Open the Library panel from the left sidebar
- Click the Upload button (or drag and drop files directly into the Library panel)
- Select the file from your local drive
- The file will appear in your Library immediately and is ready to use in any conversation
Files uploaded during a Temporary Chat are the one exception: these are never saved to your Library or account, preserving the privacy intent of temporary sessions.
How to Use Library Files in ChatGPT Conversations
Uploading files to Library is only half the feature. The real value is being able to reference those files instantly in any conversation, without hunting through old chats or re-uploading. Here is how to do it:
- Start a new conversation in ChatGPT or open an existing one
- Click the attachment icon (the + or paperclip button) in the message composer
- Select Add from Library from the menu that appears
- Browse or search for the file you want to use
- Click the file to attach it — it will appear in your message composer
- Type your prompt and send as normal
The attached file is now active in that conversation. ChatGPT can read its contents, answer questions about it, extract data, reformat it, or perform any analysis task you request. The key difference from a regular upload is that you chose the file from persistent storage rather than your local drive.
A few practical tips for getting the most from File Library:
- Rename files descriptively before uploading — Library uses your original file names for search, so “Q1-2026-report.pdf” is far easier to find than “document-final-v3.pdf”
- Reuse reference documents constantly: company style guides, product specs, brand voice docs, or research papers are ideal candidates for Library since they are referenced repeatedly
- Note that deleting a conversation does not delete your Library files — files persist independently of chats and must be deleted manually from Library
- Generated files are also saved automatically: if ChatGPT creates a spreadsheet or code file for you, that output goes into Library too, making it easy to retrieve and continue working on it
Enterprise IT teams should note that files stored in Library are subject to OpenAI’s standard data retention policies. OpenAI removes files from its servers within 30 days after you manually delete them from Library. For sensitive documents, review OpenAI’s Privacy Policy and consider whether Library storage aligns with your organization’s data handling requirements.
Common Questions — ChatGPT File Library
Q: Is ChatGPT File Library available on the free plan?
A: No — File Library is only available to ChatGPT Plus, Pro, and Business subscribers. Free-tier users cannot access it. Additionally, users in the European Economic Area, Switzerland, and the United Kingdom cannot use File Library yet due to regional regulatory requirements.
Q: Will my Library files expire or get deleted automatically?
A: Files in your ChatGPT Library do not expire automatically. They remain accessible until you manually delete them. After manual deletion, OpenAI removes files from its servers within 30 days. Notably, deleting a conversation that used a file does not delete the file from your Library.
Q: Can I use ChatGPT File Library on mobile (iOS or Android)?
A: Not yet. As of April 2026, File Library is a web-only feature accessible at chatgpt.com. The ChatGPT mobile apps for iOS and Android do not support Library access or file management. OpenAI has not announced a specific timeline for mobile support.
Q: What happens to files uploaded during Temporary Chat?
A: Files uploaded during a Temporary Chat are never saved to your Library or account. This is by design — Temporary Chat is intended for sessions that leave no trace. If you want a file saved for future use, upload it in a standard conversation or directly to the Library panel.
Conclusion
ChatGPT File Library is a straightforward but genuinely useful upgrade for anyone who uses ChatGPT with documents regularly. The three things to remember: it requires a paid subscription, it’s currently web only, and it is not available in the EEA or UK. Set it up once by uploading your most-used reference files, and you will immediately spend less time re-uploading and more time getting answers. For users in supported regions, this is one of the most practical quality-of-life improvements OpenAI has shipped in 2026.
